RCV000735916 | SCV002288759 | uncertain significance | Bardet-Biedl syndrome | 2021-03-10 | criteria provided, single submitter | clinical testing | This sequence change replaces serine with arginine at codon 375 of the BBS1 protein (p.Ser375Arg). The serine residue is weakly conserved and there is a moderate physicochemical difference between serine and arginine. This variant is not present in population databases (ExAC no frequency). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). This variant has been observed in individual(s) with clinical features of BBS1-related conditions (PMID: 30614526; Invitae). In at least one individual the data is consistent with the variant being in trans (on the opposite chromosome) from a pathogenic variant. ClinVar contains an entry for this variant (Variation ID: 585170). |
